Angry 1997 Mustang 02 sensor circuit malfuntions

I've recently removed the motor out of my car, (a 1997 GT auto) and after everything was reinstalled i can drive the car for 20 miles before i get the ses light on. It's got three codes P0136, P0141, P0156 which are all 02 circuit malfunction codes, two are for bank one sensor two and the other is bank two sensor two.The car has bbk shorty headers and off-road pipe with 02 simulators. I checked all connections and everything is connected fine. I installed all of the exhaust mods last year with zero problems and now i have no way to get the car inspected. Any help would be greatly appreciated. PS I searched the site for a similar problem and didn't find this.
